SAFE OR VAULT DOOR.

Specification of Letters latent.

Patented. July lll, i911.

Application filed August 28, 1910. Serial No. 578,994.

T o all whom it may concern:

Be it known that I, SAMUEL W. FISH, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Safe or Vault Doors, of which the following is a specification.

rlhis invention relates to safes or vaults, and especially to safe or vault doors particularly adapted for use where the safe or vault is of massive construction, the object of the invention being to provide improved means for holding and securing the door within the doorway of the vault body.

In vault doors as usually constructed it has been the practice to secure the door holding means, as for instance the bolt carrying frame, to the door by means of bolts or screws passing through such bolt frame and projecting into the inner face of the door. lt is a well known fact that although such bolted frames and the large bolts usually used for securing such frames to the door are very impressive in appearance, the strength of such construction is nevertheless dependent upon the means, or bolts, for attaching such bolt frame to the door, so that the entire door holding means is no stronger than the bolts or screws which secure the frame to the door. lt is also well understood that a door having integral holding means, as for instance lugs, now in common use, provide ideal security, but in order to use such a holding means it is necessary to have a rotary door or else to mount on the jamb of the body an internally serrated annulus, neither of which, however, is coI1-.

sidered ideal for large safe and vault doors owing, in the first instance, to the friction between the surface of the door and the jamb, and in the second instance, because the means for rotating the annulus must be mounted. on the jamb.

The object, therefore, of the present improvement is to` provide a door holding means having all of the good features of the ,lug door and without any of its objectionable features when applied to large doors, and to accomplish this l have provided a member carrying door holding lugs which may be rotated independently of the door instead of rotating the entire door, so that a non-rotating door may be used while at the same time securing it against the opening thereof by lugs, and which lugs will be so attached to the door that the resisting strength thereof will be equal to lugs which are formed integral with the door. Thus I am enabled to provide, as hereinbefore stated, a door which can be secured in position by the use of lugs while avoiding rotation of the door in the jamb of the body.

In the drawings accompanying and forming part of this specification, Figure 1 is a rear view of this improved door, a part thereof being broken away and in section; Fig. 2 is a sectional view taken in line 2 2, Fig. l; Fig. 3 is a cross-sectional view of the rotating member of the door; Fig. 4 is a cross-sectional view of the non-rotating member or door proper; Fig. 5 is a detail sectional view of a portion of the door looking in the direction of the arrow shown in Fig. ll; Fig. 6 is a detail view of a portion of one of the holding bolts; and Fig. 'T is a view of a portion of the body jamb.

Similar characters of reference indicate corresponding parts throughout the figures of the drawings.

In the present improvement the door is made up of a pair of members, one a non-rotating member and comprising the door proper or door body 2 and the other a rotatable member 3 carrying means for securing and holding the door in the doorway or jamb of the body 70, which jamb carries the door holding lugs 80. These two door members are suitably secured together by means hereinafter described, whereby they may be moved as a unitary structure in opening or closing the door, while permitting the member 3 to be rotated independently of the door for the purpose of securing the door in the jamb. These members may be made up in various forms, but in the form shown the door 2 is shown as a round or annular door comprising a body portion or main web 4 having a rearwardly extending flange 5 inclosing a. chamber and provided with annular shoulders or steps 6 and 7 adapted to engage similarly formed shoulders or steps carried by the jamb. The periphery of the door is shown as of tapered formation, and the annular flange 5 is pro vided at its inner end with interiorly located spaced apart lugs S. The exterior surface of the flange is provided with recesses 9 adjacent to the inner endy thereof, the inner ends of which recesses open at the end of the flange, each recess thus having pair of end walls and a front wall for the purpose hereinafter set forth.

The member 3, which may be made in any desired manner, is provided with lugs 10 cooperating with the lugs 8 of the member 2, whereby the two members are securely held together. This member 3 is also with lugs 11 adapted to engage similarly formed lugs carried by the vault body adjacent to the jamb thereof for securing the door in position, and therefore these lugs will be hereinafter termed door holding lugs, as contradistinguished from the lugs 8 which secure the two members together, and which will be hereinafter termed member holding lugs. The lugs 11, when the member 3 is properly rotated to secure the door in its amb, are in position to form the inner walls of the recesses 9 and thus prevent the withdrawal of the door from the body, while the walls of the recesses 9 prevent the rotation of the door within the body. That is to say, when the member 3 is rotated into such position that the spaces between the lugs 11 are in register with the recesses 9 of the door fiange it will be apparent that the door can be swung into its jamb so that the lugs on the door jamb will enter between the lugs 11 of the member 3 and into the recesses 9 of the door flange, the circumferential end walls of such recesses preventing rotation of the door member 2 but not the rotation of the member 3, such jamb lugs eing of a size to properly fit the recesses 9 of the door flange. Then when the member 3 is rotated to carry the spaces between the lugs 11 out of register with the recesses 9 and the lugs 11 into position to register with such recesses, the lugs SO of the body jamb fitting therein at this time will securely hold the door against withdrawal. j The door holding lugs 11 have about half the circumferential length of the member attaching lugs 8 and 10 to permit the rotating member 3 to be rotated from locked to unlocked position and vice versa without disengaging the two members 2 and 3 of the door. The rotating member 3 is rotatably mounted on a boss or cylindrical projection 12 at the center of the door, suitable antifriction bearings 13 being provided between the cylindrical projection l2 and the cylindrical projection let of the member 3. In practice the rotating member 3 is constructed of the form shown in section to provide increased strength.

F or locking the member 3 to the door member 2, and to prevent rotation of the member 3 at a predetermined time, suitable means is provided, which consists in the present instance of locking bolts 15. Any desired number of these bolts may be used, two or more. In the present instance the rotating member 3 is provided with a pair provided .under the control of of annular spaced apart flanges 16 and 17 having bolt apertures therein for the reception of the bolts l5, the flanges 16 and 17 thus constituting guides for the bolts. The ends of the bolts are adapted to project into the bolt openings formed in the flange 5 of the door member 2. In the present construction the bolts are shown located entirely around the rotating member 3, although, as hereinbefore stated, a less number thereof could be used. By this means the rotating member is locked to the door member 2 when the lugs 11 are in position to engage the jamb lugs S0 of the body. At this time the bolts are in position to register with their openings in the flange 5 of thc door member 2 and can be shot into position by any suitable means provided for that purpose, either automatically or otherwise, and so prevent the rotation of the member 3 and the unlocking of the door.

In the present instance the means for operating the bolts carried by the rotating member comprises a suitable gear mechanism a suitable automatic and time-lock mechanism. The rotating member 3 carries a plate or disk 1S for supporting the gear mechanism for operating the bolts. This mechanism comprises a large central gear 19 mounted on a stud 20 supported by the plate 18, suitable antifriction bearings 21 being placed between the stud and the hub of the gear. In mesh with this gear are a series of pinions 22, one for each bolt, and mounted on a stud 23 secured to the plate 18. Secured to the inner end of each bolt is a link or lever 24 having an elongated slot 25 through which the stud 23 projects, this elongated slot being provided to permit the retraction and protraction of the bolt. Each of the gears or pinions 22is provided with a pin 26 projecting into an elongated opening 27 of the link 21, so that as the pinion is rotated by the large central gear it will protract or retract the bolts in a manner which will be readily understood.

As hereinbefore stated, various means may be used for rotating the large central gear thereby to shoot o'r Withdraw the bolts, but in the present instance 'this gear is under the control of a suitable automatic and time-lock mechanism such as is in common use. The automatic 30 and time lock 31 are mounted on a plate 32 .supported by studs 33 projecting from the plate 1S. The automatic is operatively connected with a rack bar 34, it being effective to reciprocate this bar in one direction on being' set and in. the opposite direction automatically. This rack bar is in engagement with a pair of pinions 22, so that when the bar is shifted the pinions will be rotated and thereby the central gear rotated to rotate the pinions 22 and protract or retract the bolts.

Tn operating this mechanism the time lock is first wound and then the automatic bolt operating device 30 properly set, at which time the door is ready for closing.

' t is necessary, however, to provide means for releasing the automatic thereby to permit the same to shift the rack bar and so protract the bolts as soon the rotative member 3 is rotated into locked position by the means hereinafter described. For this purpose a lever 35 is provided, see lfig, 1, in position to come in contact with a projection S1 on the inner face of the body jamb during the rotation of the member 3. This lever is so positioned and connected as to release a catch 36, which in turn allows the rack bar 3a to be forced by the protracting springs of the automatic into such position as to rotate the gears or pinions 22 and therethrough the central, gear and thereby the pinions 22 and so protract the locking bolts and thus lock the rotative member 3 and the door member 2 together against rotation of the member 3 independently of the door. lt will be understood of course that various means might be used, as hereinbefore stated, for protracting and retracting the bolts. Tn the present construction, when the time lock has run down the automatic will automatically shift the rack bar in the opposite direction and so retract the bolts and permit the rotation of the member 3 by the means provided for that purpose, to unlock the door. Tt will also be understood that the rotation of this member 3 may be controlled by a suitable combination lock such as is known as a day lock.

For rotating` the member 3 to carry the lugs thereof into position to lock the doo-r against withdrawal and to also carry the locking bolts 15 in position to lock the two members 2 and 3 together, suitable means may be provided, automatic or otherwise. In the present instance this means comprises a spindle el() projecting through the door web and in position to be operated by a suitable crank. The inner end of this spin dle carries a geared nut l11 in mesh with a geared segment il?. carried by the flange 17 of the rotating member 3, whereby, on rotating the spindle, the member 3 will be rotated to carry its lugs into or out of position to register with the lugs of the body j amb and into position to permit the bolts 15 to register with the openings in the flange 5 of the door member 2, or out of position to register therewith as the case may be. This geared nut l1 will be keyed to the spindle in any suitable manner. Thus it will be observed that by rotating the spindle 40 the member 3 will be rotated, together with its locking bolts and door holding lugs, and all of the mechanism designed to operate the bolts and control the operation thereof relatively to the door proper, so that the door may be swung` into and out of the door way and securely held within the jamb of the 'body without the necessity of rotating the massive structure, while it will be as securely held by the provision of holding lugs as though such lugs were formed integral with the door and the door rotated to engage the lugs carried thereby with the jamb lugs. By the provision of this improved door it will be immediately apparent that the door proper may be made of unmachineable metal while the rotating member may be made of a machineable metal, thus very, much facilitating the construction and setting up of the operating parts, as well as very materially lessening the cost thereof. Furthermore, it will also be observed that the locking bolts 15 are so located that the ends thereof are protected by the flange 5, so that it would be an impossibility to force nitro-glycerin into the door joint and against the ends of the bolts in order to retract the same, since the bolts and the ends thereof are entirely protected against any1 action of explosives at the door joint, as the ends of the bolts do not project through the flange or to the exterior surface thereof.

ln practice some suitable non-conducting` material 50 may be located between a plate 51 and the web 4 of the door. The bolt operating mechanism will also be covered in practice with a suitable glass covering, in the usual manner, to keep dirt and dust from the mechanism, and this covering may be provided with a hinged door 54 to give access to the bolt operating mechanism and the time lock and automatic.

It will be understood, of course, that instead of operating the bolts 15 by an automatic in the manner shown various other ways, as by means of spindles, could be provided for this purpose if preferred, so that the 'bolt operating mechanism may be considered either as a full automatic, as semi-automatic, or one entirely controlled by spindles from the outside, as may be preferred.

In practice, instead of mounting the rotating member 3 centrally of the member 2 inthe manner shown, it will be obvious that suitable antifriction bearings might be located between the, flange 17 and the flange 5 of the door, and thus the central bearing of this rotating member 3 entirely done away with. The bolt openings in the flange 5 will be provided with soft metal inserts in the usual manner.

From the foregoing it will. be observed that I am able to provide a door which may be secured within its doorway by holding lugs without the necessity of rotating a massive door, thus combining with an ordinary swinging non-rotating member or door all the advantageous features of one secured in position by lugs.
